The activities of four colonies of Plebeia saiqui (Holmberg, 1903), of São Francisco de Paula, Rio Grande do Sul, Brazil, were studied from October, 1998 to September. 1999, comparatively during the oviposition period and the diapause. The construction of the cells was monitored by direct observation of the nests. The duration of the diapause period varied from 76 to 168 days. Monthly, the bees that left and entered were counted for 10 minutes, at each hour, during the complete period of flight activity. Influence of meteorological factors on the activities of bees flight was analyzed through simple and multiple regressions. During the oviposition period was found that solar irradiation, temperature and relative humidity had a significant influence on bees... |

Melipona bicolor schencki occurs in southern Brazil and at high elevations in southeastern Brazil. It has potential for use in meliponiculture but this stingless bee species is vulnerable to extinction and we have little knowledge about its ecology. In order to gather essential information for species conservation and management, we made a study of seasonal flight activities in its natural environment. We sampled bees entering the nests with pollen, nectar/water and resin/mud, in five colonies during each season. In parallel, we analyzed the influence of hour of the day and meteorological factors on flight activity. Flights were most intense during spring and summer, with daily mean estimates of 2,100 and 2,333 flights respectively, while in fall and... |
